DRYING APPARATUS.

Specification of Letters Patent.

Application filed July 10, 1918. Serial No. 244,184.

To all whom it may concern.

Be it known that we, FRANK PATRONO and NIGOLA PATRONO, citizens of the United States, and residents of Mount Vernon, in the county of lVestohester'and State of New York, have. ointly invented certain new and useful Improvements in Drying Apparatus, of which the following is a specification.

This invention relates to a drymgapparatus with which are produced air streams which continually vary in direction and also flow in reversed directions. The apparatus is adapted to dry paste, commercially known as 11130910111, and for other purposes.

Its organization: comprises essentially a pair of rotating fan wheels which rotate about their axes. The fan wheels can rotate in the same direction to produce streams of air in one direction, or the fan wheels can be rotated in opposite directions to produce streams of air in one direction with one fan wheel and streams of air in an opposite direction with the other fan wheel. In the former case the drying apparatus is located at one end of the material to be dried, and in the latter case the material is located, one portion on one side and the other portion on the opposite side of the apparatus.

In the accompanying drawings Figure 1 represents a front elevation of an exemplification of the'drying apparatus partly in vertical section and Fig. 2 shows an end view of Fig. 1.

A pair of similar A-shaped frames 20 and 21 have each the top member 23 and the cross member 24. Upon the top members 23 are secured the pillow blocks 25 and 26 and upon the cross members 24 are secured the pillow blocks 27 A tubular driving shaft 29 is journaled in the pillow blocks 27 and has fastened thereto the pulleys 30, 31 and 32. Collars 33 and 34 are fastened to the tubular shaft 29 and abut against the pillow blocks 27. A supporting shaft 36 is j ournaled in the pillow blocks 25 and 26 and a tubular shaft 37 is concentric with and journaled on the supporting shaft 36. A collar 38 is fastened to shaft 36 and bears between an end face of the pillow block 25 and the adjacent end' of the tubular shaft 7 37. A collar 39 is fastened to the shaft 36 and bears against an end face of the pillow block 26.

A double groove pulley 43 with the circumferential grooves 44 and 45 is secured to the shaft 36 and a face of its hub bears against the adjacent end of the tubular shaft 37.

Across 46 is concentric with and fastened to the tubular shaft 37. A pair of tubular arms 47 are at one end in threaded engagement with said cross. At the other ends of said arms are secured in threaded engagement journal bearings comprising each a T 48. Rollers 49 are located ineach T 48, and form bearings for the axles 50 and 51. Collars'52 are fastened to the axles 50 and 51 and bear against the opposite ends of the Ts 48.

A-fan wheel 55 is fastened to one end of the axle 50and a pulley56is fastened to the other end of said axle. A fan wheel 58 is fastened to one end and the pulley 59 is fastened to the other end of the axle 51. A straight belt 60 connects the groove 45 of the pulley 43 with the pulley 56 and a cross belt 61 connects the groove 44 of the pulley 43 with the pulley 59. Pairs of tie rods 62 connect the cross 46 with the Ts 48. Struts 65 having the collars 66 extend from the cross 46 and tie rods 67 have their ends secured to the Ts 48. Openings in the middle portions of the tie rods 67 engage the ends of the struts 65 and bear against the collars 66.

A pulley 69 is fastened to the tubular shaft 37 and a pulley 70 is fastened to the shaft 36. A belt 71 connects the pulleys 30 and 69 and a belt 72 connects the pulleys 32 and 70.

To use the drying apparatus the pulley 31 is rotated by a belt not shown, and causes the tubular driving shaft 29 to turn. Rotation is transmitted by the belt 72 from the pulley 32 to the pulley 70 and hence to the supporting shaft 36, which causes the double groove pulley 43 to turn. Rotation is transmitted from the pulley 30 to the pulley 69 by means of the belt 71, which causes the tubular shaft 37 to turn. The rotations of the pulley 43 are transmitted, by means of the belts 60 and 61 respectively, to

the pulleys 56 and 59, turning the former in one direction and the latter in an opposite direction. By the disposition of elements described the fan wheels 55 and 58 rotate on the axis of their axles 50 and 51, an d the latter revolve around the axis of the shafts 86 and 37 If it is desired to rotate Patented May 4, 1920. v

both fan wheels in the same direction a straight belt is substituted for the cross belt 61.

Having described our invention what we desire to secure by Letters Patent and claim 1s:

1. In a drying apparatus the combination of a rotating supporting shaft, a tubular shaft journaled on the supporting shaft, a cross secured to the tubular shaft, a pair of tubular arms with one end of each extending from said cross, a T supported on the other end of each tubular arm, two pairs of tie rods connecting said cross and said Ts, a pair of tie rods with one end of each connected to one of said Ts and their other ends fastened to the other T, a pair of struts ex tending from said cross and supporting the central portion of the latter tie rods, an axle journaled in each T, a fan wheel fastened to each axle and means to rotate said fan wheels from said supporting shaft.

2. In a drying apparatus the combination of a pair of frames, pillow blocks supported on the frames, a rotating driving I shaft journaled in said pillow blocks, a pair of pulleys fastened to the driving shaft, a

second pair of pillow blocks on the frame, a supporting shaft journaled in the second pair of pillow blocks, a single pulley and a double groove pulley fastened to the sup porting shaft, a tubular shaft journaled on the supporting shaft, a pulley fastened to the tubular shaft, a cross fastened to the tubular shaft, arms extending from the cross, a T for a ournal bearing at the outer end of each arm, an axle journaled in each journal bearing, a fan wheel fastened to one end of each axle and a pulley at the other end, a belt connecting each of the latter pulleys with the double pulley on the supporting shaft,

a belt connecting the pulley on the tubular shaft with the pulley on the driving shaft, and a belt connecting the single pulley on the supporting shaft with the other pulley on the drivin shaft. Signed at Mbunt Vernon, in the county of lVestchester and State of New York, this 2nd day of July, A. D. 1918.
